I’ve studied the bp-xprofile-signup.php file, but in the code the fullname value is part of an array (?) identified by field_id, which I know is ‘1’ for fullname, but there I get lost, way too complicated php stuff for me. Something like this?!:

$fields = BP_XProfile_Field::get_signup_fields();

if ( $fields ) {
foreach ( $fields as $field ) {

$value = $_POST['field_' . $field->id];

$field->id = '1';

$fullname = $value;

Please help if anyone can. If I can figure this out, I can probably solve several other problems I have been boring you with for the last few months.
